Effects of carbohydrate forms on running performance
Running Performance in Response to Different Forms of Carbohydrate
NA · University of Georgia · NCT06742398
This study tests whether using different forms of carbohydrates, like a mouth rinse or dissolvable strip, can help trained runners perform better in a 12.8 km race.

What this trial studies
This intervention examines how different forms of carbohydrates, specifically a carbohydrate mouth rinse and a dissolvable strip, influence running performance during a 12.8 km time trial. The study employs a randomized, controlled crossover design with endurance-trained athletes, who will participate in multiple testing visits where they will consume either a carbohydrate solution, a water solution, or a carbohydrate strip before running. The primary focus is to assess performance improvements and physiological responses, such as heart rate and blood lactate levels, while controlling for variables like menstrual cycle phases in female participants.
Who should consider this trial
Good fit: Ideal candidates are endurance-trained athletes aged 18-45 with a normal BMI who train regularly.
Not a fit: Patients on low carbohydrate diets or with chronic diseases may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could enhance athletic performance by identifying optimal carbohydrate delivery methods during exercise.
How similar studies have performed: Previous studies have shown positive effects of carbohydrate intake on exercise performance, suggesting this approach is supported by existing research.
